WINDSHIELD.

Application filed June 17, 1926. Serial No. 116,509.

comes coated with ice or snow and vision therethrough becomes impairedor totally obstructed. The windshield wipers available are not able tomaintain a clear vision portion on the outer surface when the snowfallis "heavy or when the samefreezes and it isan object of the: presentinvention to provide a structure which will enable the driver to see theroad ahead and approaching traflic under all conditions.

The manner in which this is-done is by providing a" portion ofthewindshield with aslide which may be raised or lowered to produce anopenspace therein, in the line of vision ofthe operator.

g It is a further object of this invention to provide awindshield "ofthe above character whichfis essentially clear vision, all obstructingportions being eliminated.

Further objects and advantages will be pointed out as the descriptionproceeds, reference being had now to the accompanying drawings formingapart hereof, wherein;

Figure v1 is a section on the line 1- -1 of Figure 2, and looking in thedirection of the arrows. i v e j Figure 2 is a front elevation of oneform of the device. i

Figure 7 is a front elevation of another form of my device.

Figure 8 is a section on the line 88 of Figure 7and looking in thedirection of the arrows.

Figure 9 is a section on the line 9-9 of Figure 7 and looking in thedirection of the arrows.

Figure 10 is a section on the line 10-10 of-Figure 7 showing a modifiedway of mounting the sliding pane.

In F gure l a represents the standards or uprights of the vehicle bodyupon which side panes b are pivotally mounted. These panes may besecured in a desired position by means of links Z/and screws b which aresecured to the pane and frame, respectively, and enable the window tobeadjusted for a suitable degree of ventilation. The top of the car isindicated at a and the cowl at a The front pane or windshield consistsof three sections 0, c and 0 the first two of which are permanentlysecured between the cowl and top in the following manner and the thirdslidably mounted between the two as hereinafter described.

Referring more particularly to Figuresfi, 6 and Utne top is cutaway toform two sides of a housing as indicated at a within which an innerhousing (1 is clainpedby a face plate a. 1n the inner housing d a blockof rubber orother non-metallic and resilient substance a! is providedand this serves as a cushioning element between the pression and betweenthis seat and the glass aliner of rubber or othersuitable material of ispositioned. The glass is held in such position within the aperture a .ofthe outer housing and is cushioned in an obvious manner by the abovedescribed structure.

At the cowl,'the glass is secured in a recessed portion a in which ahousing 6, similar to d is clamped by face plate a which bearson theupper portion of the frame above the dash. Between this plate and thecowl is an aperture or slot or within which the glass rests. The loweredge of the glass is secured similarly to the upper edge by block 6,seat e and liner e v The front portions of the windshield comprising thethree sections are secured together by suitable means which do notobstruct the vision. One form of such means is shown in Figures 1 and 2wherein strips of glass f are cemented to the stationary portions 0 andc and thus supply grooves in which the movable pane may slide. InFigures 7 and 10 another form is shown wherein the stationary panes aregrooved as i at 0 along the vertical edges 0. The sliding pane hastongues a" groove to slide therein.

In order to prevent water from flowing down the pane and into thehousing, a bead g of rubber or other suitable material is positioned bystrip g to bear against the glass and provide a water tight joint. Inthe form where the window is raised upwardly the bead may be integralwith the liner 0 as shown in Figure 9.

To'raise or lower the window in the form shown in Figures 1 through 6, abracket h is secured to or formed integral with the seat or clamp h atthe lower edge of the pane and terminates in an inwardly extending toe7L2. The bracket is slotted at h to permit it to slide by the operatingshaft.

An operating shaft z' is mounted in a bearing hub j which is secured tothe dash of the vehicle. On the operating side of the dash a hand wheel2" is keyed to the shaft and on the opposed face of the bearing hubthere are provided radial grooves y" in which a pin 2' may rest. Thispin is made to yieldingly engage the grooves by a means to behereinafter described.

A hub 71 is mounted on the shaft '5 and is slidably ke ed thereto. Anapron k which is carried y the cowl serves as a bearin for the hub and aspri around the shaft '2 engages the hub an is compressed by washer heldby the pin 11". This sprin serves to hold the pin in any slot to whic ithas been moved.

Secured to thebracket h by eye-bolt h and adjustable eye it is aflexible cord l which takes one turnover the hub 2' and is placed undertension by taps h on the eye it". It will thus be seen that when thehand wheel i is pulled out and turned, the sliding pane will be movedaccordingly.

Below the apron 'k is provided a channel m which collects any waterwhich might pass between the glass and the cowl and a pipe m carries thecollected water off, as shown in Figure 2.

In' Figure 8 a mechanism is shown for positioning the upwardly slidingpane of Figure 7. This structure consists of brackets n which aresecured to the vehicle top a and which mount a shaft 0 which may beintegral with a lever p having a crank arm p. Link 9 connects the crankarm with the top of the window. The'lever p is provided with a handle 19and turning with the shaft which engage the 0 is a flange 0 having limitlugs 0. These lugs engage a stud n in which is contained a springpressed detent n which engages depressions 0 in the flange .0 to holdthe glass in a desired position. The pane may be lifted to a desiredosition by the handle 2 Either of the aliove types may be used,depending upon the convenience of the operator and the invention is notto be limited save as set forth in the appended claims.

What I claim is:

1. In a vehicle windshield, a fixed portion, a movable portion, a shaftrotatably mounted on the vehicle dash, means to turn the shaft, meansselectively to hold the shaft ina turned position, and an impositiveconnection between the shaft and the movable portion for transmittingmovement of the former to the latter.

2. In a vehicle windshield, a fixed portion, a movable portion, a shaftrotatably mounted on the ve'lncle dash, means to turn the shaft, meansto hold the shaft in a turned position, a bracket on' the movableortion, and a flexible cord passing around the shaft and secured at itsends to the bracket.

3. In a vehicle windshield, a fixed portion, a movable portion, a shaftrotatably mounted on the vehicle dash, means-t0 turn the shaft,

means to hold the shaft in a turned position,

a bracket on the movable portion, a slot in the bracket through whichthe shaft passes, ahub on the shaft, a flexible cord passing around thehub, and means for securing the cprd to the bracket adjacent the ends ofthe s 0t.

4. In a vehicle windshield, a fixed portion amo-vable portion, ashaft'rotatably mounted on the vehicle dash, a bearin for'moun the shaftin the dash, a ham wheel scour to the ihaft, a p11;1 on the ilgaft,radial slots intie earin an en a e leb the a hub 'slidably keyed t5 aleshaft, 8 mounted on the shaft and bearing against the hub to yieldinglyengage the pin with the adjacent slot in the bearing, a bracket on themovable portion of the windshield, a slot in the bracket through whichthe shaft and hub extend, a flexible cord passing around the hub, andmeans to secure the cord to the bracket adjacent the ,ends thereof.
